Research direction

The payload names no file, so start by finding where the Debian package dependencies (libc6, libqt6core6t64, libssl4) are declared in the repository's packaging configuration. Compare those minimum versions with what Ubuntu 26.04 ships (libc6 2.43, Qt 6.10.2). Done when a build targeting 26.04 installs with dpkg without unmet dependencies. Check with a maintainer first whether the pinned versions are intentional.

Describe the Bug

dpkg install fails with latest prerelease debs (1113 and 1114) on Ubuntu 26.04. 1111 is the last installable version. IIRC the libssl4 is something that has only showed up in Ubuntu 26.10. I keep this machine aggressively up to date but haven't deviated out of the standard LTS package regime.

Preparing to unpack sunshine_2026.1114.155648-1+ubuntu26.10_amd64.deb…
Unpacking sunshine (2026.1114.155648-1+ubuntu26.10) over (2026.1109.513-1+ubuntu26.04)…
dpkg: dependency problems prevent configuration of sunshine:
sunshine depends on libc6 (>= 2.44); however:
Version of libc6:amd64 on system is 2.43-2ubuntu2.4.
sunshine depends on libqt6core6t64 (>= 6.11.2); however:
Version of libqt6core6t64:amd64 on system is 6.10.2+dfsg-7.
sunshine depends on libssl4 (>= 4.0.0); however:
Package libssl4 is not installed.

Expected Behavior

Sunshine uses dependencies available on a standard Ubuntu 26.04 LTS install.
